usb: chipidea: move ci_ulpi_init after the phy initialization
The function ci_usb_phy_init is already handling the hw_phymode_configure path which is also only possible after we have a valid phy. So we move the ci_ulpi_init after the phy initialization to be really sure to be able to communicate with the ulpi phy.
